BACKGROUND OF INVENTION

a. Field of Invention

The invention relates generally to footwear devices that enhance users'situations wherein an anchor foot and a pivot foot are needed, such asin baseball, softball, golf, kicking, e.g., as in football, and othersituations where same foot pivoting is necessary. More particularly, thepresent invention is a pair of sports shoes wherein one of the left footand right foot has function-enhancing anchoring patterns on its sole andthe other of the left foot and right foot has function-enhancingpivoting patterns on its sole.

b. Description of Related Art

The following patents are representative of sports shoe designs:

U.S. Pat. No. 7,165,344 B2 to Blackwell describes a “RED e” cleat thatis a disposable, self-adhesive, all-surface footwear cleat having anon-skid gripping surface, designed to address all sport, game, play andwork foot-traction requirements. The “RED e” cleat replaces the need forspecialty footwear, which incorporates permanently implanted or attacheddevices for affixing traction gear to the underside of shoes. The cleatsattach simply and quickly to the sole and heel area of any footwear.Removal of the cleat is also simple. By sliding a flat-edged toolbetween the cleat and the surface of the footwear to break the seal, thecleat will peal away leaving the footwear ready for other uses.

U.S. Pat. No. 6,817,117 B1 to Campbell describes an outsole for anathletic shoe, in particular a golf shoe, having a plurality of tractionelements of resisting rotational movement parallel to a plane surface ofthe ground. Traction elements in a forefoot region of the outsole areoriented with resist surfaces facing a lateral edge and tractionelements in a rearfoot region of the outsole are oriented with resistsurfaces a medial direction. The resist surfaces of the tractionelements are substantially perpendicular to a base surface of theoutsole and other surfaces of the traction element can be connected tothe base surface by concave curvatures.

The shoe sole defines adepressed footbed surface for a lower center of gravity and increasedstability during golfing play. The closure assembly, in a first, wearingcondition, resiliently engages across the wearer's foot to provide asecure fit during golfing play, and, in a second, donning or doffingcondition, resiliently expands to facilitate passage of the wearer'sfoot into and out of the volume. The closure element includes a tonguehaving side edges attached to the upper, and the tongue has a upper endportion defining a surface positioned to resiliently engage upon anankle surface above the wearer's foot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 shows a side view of a preferred embodiment present inventionsports shoe 31 with sole 35, and any shoe top, such as shoe top 57 andtop plate 61, with lacing 63. Lacing 63 may be tightened and secured bybutton lock 65. FIG. 2 and FIG. 3 show pivot foot sole and anchor footsole spike arrangements, respectively, and either of these soles couldbe incorporated into the present invention sports shoe 31 of FIG. 1.However, in FIG. 1, a side view of sole 35 is presented, and this sole35 is shown in its bottom view in FIG. 2.

Referring to both FIGS. 1 and 2, wherein identical parts may beidentically numbered, the toe or forward area 43 of the sole 35 includesa plurality of spikes that are collectively in the form of a spacedapart herring bone pattern. These include spikes such as spikes 51, 53,45, 47, 73, 83 and 89. There is a central spike track 85 toward thecenter of the sole 35 on forward area 43. Additionally, there are twosets of symmetrical arcs that form broken concentric circles. These arearc sets 75, 77, 79 and 81. They act as a set of pivoting spikes of theback foot during a baseball or softball bat swing, a golf swing or otherpivoting movement. Middle section 37 is a relatively smooth area thatmay be preferably more flexible for the bending of the shoe. Heel area39 includes an extended U-shaped spike 87, as well as a plurality ofV-shaped spikes, such as spikes 71 and 41. Heel area 39 also hasherringbone or opposing diagonal spikes, such as spike 69.
